This is a very mature app that we have deployed in many sites. The
older sites run CentOS 6 and use apache and modwsgi. The newer sites
run CentOS 7 and use nginx and uWSGI. So we am very familiar with
their respective setups. But I have never used anything other then the
out of the box python that came with the OS. So I am not sure how to
get that nor if it will break anything. I am going to investigate Pete
Biggs' suggestion to use Software Collections.
